Sold - thanks.

@Rex-Lightning: I have sent you a private message.

Sorry, these are now SOLD.

@jeffmccosker: good to see a new episode of this setting! crazy how easy you make these huge gaps look!

For those of you with access to a 3D printer who like to print/modify the FlightFender-SlotCover/FlightShield-Holder, here is the link:

By the way:
For covering the slots and providing a little bit of an improved lock-in for mounting the FlightFender inside, I have created two little parts for 3D printing. I am going to share it tomorrow (just registered to thingiverse, this requires 24h of wait until I am allowed to share something).

I do also have the FullFlight set (FlightFender + FlightFins + FlightShield) and like the quality very much - I think the two brothers really did a great job and this is worth the money.

However, I decided for the moment not to use the FlightFins, because It is unlikely that I will start to hurt myself with jumps that high that would require FlightFins - I am more into offroading and my kind of jumps are basically only drops. Furthermore to jump with the FlightFins one would have to lock its feet very close to the middle, which for my style of riding feels strange, because I am used to a very wide stance.
So for my usage the FlightFins would only help for hopping up some edges. For those rare moments (which would require changing my stance) I decided not to trade in the chance of hurting myself, because I am a little bit affraid I might stay locked in during one of my (many) bails that I usually run out.
That said, I am sure those (impressive good quality things) will find a lot of fans from the young guns going wild with jumps.

But the FlightFenders are perfect for me. I like seeing the wheel, that´s why I love this fender for it awesome look. Also they are perfect for offroad riding. I get rid of most of the little stones and dirt coming from the tire and I do not have to be afraid of damaging the fender when the board rolls over, because of its clever design.

Also the FlightShield is perfect for my usage, because I need a fender only 5% of the time and for this it perfectly does the job. It´s just so nice to have this very small thing in the bag and attach it in 5 seconds.

@cr4p: since nobody replied to my question, and in the meantime I do have an XR myself:

300km on it and gladly no ferrit rattle (not even in hard offroad) - I might be lucky, but I want to believe that they finally managed to solve this issue after the kickstarter version, the original OW and the OW+ (had all of them).

despite this was mainly a noise issue (which also only appeared in rough terrain and bumps) and did not cause any real problems, I am still happy that the XR is finally quiet in all conditions...

...and of course you have to be logged in too;-)

@djtherick2020: of course this is a way, but with that workaround you are loosing range & agility even during the time you do not need the suspension...
